Air surrounding the mountain range is cooler (because of the height) that results in the cooling of water vapors in the air that fall in the form of snow and rain.
What is the general weather of hilly area?
The places around Himalayan belt are low in temperature due to the chills they receive from the snow covered slopes. The entire region from Jammu Kashmir, Himachal Pradesh, Uttarakhand to Sikkim, Arunachal Pradesh remain moderately cold even in summers.
What occurs in hilly areas?
Land Sliding – A Most Common Disaster In Hilly Areas. The sliding down of a piece of land under the force of the gravitational pull of a mountain or hillside is called the landslide. It is a natural process which takes place in form of downward mass movements of rock, debris, and soil due to gravity influence.
Does it rain more in hilly areas?
They receive more rainfall than low lying areas because the temperature on top of mountains is lower than the temperature at sea level.
Why is the temperature low in hilly areas?
At sea level, the atmospheric pressure is more and in a HILL STATION the Atmospheric pressure is comparatively LESS. As Pressure decreases ,the Temperature also Decreases. … The water vapour present at HILL STATIONS is LESS so there is less absorption of HEAT from the SUN which prevents the rise of temperature.
Why is it cold in Baguio City?
The cold weather is caused by “amihan,” or cool northeast monsoon season that prevails between October and early March, Pagasa said. Last year, the coldest temperature recorded was 9.4°C degrees, the lowest so far in the last three years. The coldest temperature ever registered here was at 6.
What occurs in hilly areas due to cloudburst or heavy rains?
Landslides, flash floods,soil erosion occur in hilly areas due to cloudburst or heavy rains.
Why landslides occur in hilly areas?
When earthquakes occur on areas with steep slopes, many times the soil slips causing landslides. Furthermore, ashen debris flows caused by earthquakes can also trigger mass movement of soil. Heavy Rainfall: When sloped areas become completely saturated by heavy rainfall many times landslides can occur.
What is the cause of landslides in hilly areas?
Landslides can be initiated in slopes already on the verge of movement by rainfall, snowmelt, changes in water level, stream erosion, changes in ground water, earthquakes, volcanic activity, disturbance by human activities, or any combination of these factors.
Which is the coldest place in India?
Coldest – Dras
This scenic town lies between Kargil town and Zoji La Pass, also known as the Gateway to Ladakh. Sitting at a height of 10800 ft, the average temperature recorded here is -23 degree Celsius, making it India’s coldest place, which can be visited by tourists.
Which plants grow in hilly areas?

- Spruce.
- Apple.
- Tea.

What is the climate of hilly region?
Describe the Climate of Hilly region.
The Climate is moderate in Hilly region. It is hot in summer and cold in winter. Plently of rainfall takes place in monsoon season. Uttis, Salla, rhodendendron, etc are the natural vegetations.
What is the reason behind snowfall?
Snow forms when tiny ice crystals in clouds stick together to become snowflakes. If enough crystals stick together, they’ll become heavy enough to fall to the ground. Snowflakes that descend through moist air that is slightly warmer than 0 °C will melt around the edges and stick together to produce big flakes.
What causes snow to form?
Snow forms when the atmospheric temperature is at or below freezing (0 degrees Celsius or 32 degrees Fahrenheit) and there is a minimum amount of moisture in the air. … Snow can occur even at incredibly low temperatures as long as there is some source of moisture and some way to lift or cool the air.
What is the cause of snowfall in Himalayan Region?
During winter, low-pressure weather systems advance into the Himalayas from the west and cause heavy snowfall. Within the regions where western disturbances are felt, condensation occurs in upper air levels, and, as a result, precipitation is much greater over the high mountains.
What are the 4 types of landslides?
Landslides are part of a more general erosion or surficial pro- cess known as mass wasting, which is simply the downslope movement of earth or surface materials due to gravity. They are classified into four main types: fall and toppling, slides (rotational and translational), flows and creep.
How can we prevent landslides in hilly areas?
The preventive measures that can be taken to avoid landslide in hilly area:
- By providing efficient surface and cross drainage.
- By providing sub-surface drains at foot of the hill slope to control seepage flow.
- By providing benching to soil slope.
What are the effects of landslides?
The impact of a landslide can be extensive, including loss of life, destruction of infrastructure, damage to land and loss of natural resources. Landslide material can also block rivers and increase the risk of floods.
What effect does cloudburst have?
Cloudbursts cause flash floods. Flash floods in turn, uproot trees, trigger soil erosion, landslides and landslips leading to habitat destruction, and massive loss of property. Downstream, the floodwaters slow down and deposit large amounts of silt that may choke the mouth of water bodies and/or raise the riverbed.
What happens when a cloudburst?
Cloudburst, a sudden, very heavy rainfall, usually local in nature and of brief duration. Most so-called cloudbursts occur in connection with thunderstorms. In these storms there are violent uprushes of air, which at times prevent the condensing raindrops from falling to the ground.
What is a cloudburst answer?
Answer: cloudburst is sudden copious rainfall. It is a sudden aggressive rainstorm falling for a short period of time limited to a small geographical area. Meteorologists say the rain from a cloudburst is usually of the shower type with a fall rate equal to or greater than 100 mm (4.94 inches) per hour.
Which is colder Baguio or Tagaytay?
Temperatures in Tagaytay rarely venture close to 30°, with year-round temperatures that are only a bit warmer that Baguio. It’s known for its many restaurants whose views of Taal Volcano make it the perfect escape from Metro Manila.
Is it always cold in Baguio?
